Katy Perry Unleashes Her ‘Beast of Burden’ With a Pair of Stones

Pop megastar joined Ronnie Wood, Jagger onstage in Vegas

Tickets to the Rolling Stones “50 and Counting” tour aren’t cheap — and they are selling, we’re told — so it’s only right that the iconic rock’n’rollers pepper their sets with appearances from a broad range of stunning (and possibly pricey) guest performances. We’ve seen them perform “Little Red Rocket” with Tom Waits, and reported appearances from Gwen Stefani, Keith Urban, and more. But Saturday night (May 11) at their Las Vegas gig, the band summoned none other than Katy Perry. The Killer Queen joined Mick Jagger for a heated duet of “Beast of Burden” and accompanied Ronnie Wood while he soloed, offering clutch gyrational support. And, of course, she went toe to toe with Mr. Moves himself in a flurry of pomp and strut.
